MaxFlo 3 Control Valves

Main Features• Low breakout torque for smooth control and longer life

• Safest shaft blowout protection available – shaft will not fit through bonnet

• Tight bi-directional shutoff – Metal seats, Class IV; Soft seats, Class VI

• Higher flow rates; no crossover shaft to block flow path

• Sealed bearing design available

• O2 compatible design available

End Connections / Face-to-face• Integral flanges, ANSI/ISA-75.08.02, EN 558-1/2 Series 36, IEC

60534-3-2 (1˝-12˝, DN 25-300, Class 150 and 300)

• Flangeless, ANSI/ISA-75.08.02, EN 558-1/2 Series 36, IEC 60534-3-2 (1˝-8˝, DN 25-200 Class 150 and 300)

• Integral flanges, ANSI/ISA-75.08.01, EN 558-1/2 Series 37-38, IEC 60534-3-1 (Size 1˝-12˝, DN 25-300, Class 150 and 300)

• Integral Flanges, DIN 3202 F1 (DN 25 to 300, PN 16 and PN 40)

Exceptionally Fine Control• 160:1 rangeability for MaxFlo 3, compared to 50:1 for globe

valves and 20:1 for butterfly valves

• Low-friction bearings

• Low breakout torque

• Strong, backlash-free, polygon stem-plug connection

Trim OptionsReduce trim by changing only the seat ring – plug stays the same
